how to nest multiple classes and deserialize those from xml

[aeldemery]

how to make the following work

require "xmlt"

XML_FRAGMET = <<-XML
<repository version="1.2">
  <version>2</version>
  <element>
    <name>test</name>
  </element>
  <element>
    <name>test2</name>
  </element>
</repository>
XML

class Element
  include XMLT::Serializable

  property name : String
end

class Repository
  include XMLT::Serializable

  property version : String

  @[XMLT::Field(new_root: "element")]
  property elements : Array(Element)
end

module Txmltest
  repo = Repository.from_xml XML_FRAGMET, root: "repository"
  p! repo.version
  if elements = repo.elements
    elements.each do |elm|
      p! elm
    end
  end
end

I get the following error

~/P/C/txmltest (main) [1]> shards run

Error: no overload matches 'Array(Element).new' with types XML::Node, root: String

Overloads are:
 - Array(T).new(size : Int, value : T)
 - Array(T).new(initial_capacity : Int)
 - Array(T).new()
 - Array(T).new(size : Int, & : (Int32 -> T))
